To all whom it magi concern:

Be it known that I, JOHN TQEADY, a citizen of the United States,residing at Can, rollton, in the county of Carroll and State of-Georgia, have invented a new and useful Attachment for RoadMachines, ofwhich the following is a specification.

The invention relates to an attachment for road grading andscrapingxmachines.

J portions of the scraper, as clearly illusto the scraper.

openin The object of the present invention is to to the scraper ofa roadmachine, and capable of enabling the latter to tear down embankments atthe side of a road, and 'effectually tear up gravel-1y and other hard.

ground.

' With these and other objects in View, the

invention consists in the construction and novel combination of partshereinafter fully described, illustrated in the accompanying drawing,and pointed out in the claimshereto appended; it being understood thatvarious changes in the form proportion, size and minor details ofconstruction, within the scope of the claims, may be resorted to withoutdeparting from the spirit or sacrificing any of the advantages of theinvention.

In the drawing z-F igure 1 is a perspective viewof a scraper providedwith an attachment, constructed in accordance with this invention. Fig.2 is a horizontal sectional viewv of the same. Fig. 3 is a verticalsectional view on the line 3'3 of Fig. 2.

Like numerals of reference designate corresponding parts in all thefigures of the drawing.

1 designates a plurality of brackets, consisting preferably of malleablecastings and mounted on a. scraper. 2 at the rear end thereof, andlocated at the center and'end trated in Fig. 1 of the drawing. Thebrackets, which are sectional, are provided at their inner or front endswith laterally projecting flanges 3, which are piercedby sultable fasetening devices 4 for securing the brackets The outer or rear ends of thebrackets are equipped with removable plates or sections 5, secured tothe body portions of the bracket by'means of bolts 6, or other suitablefastening devices, The body portions of the brackets are bifurcated attheir rear' ends to form alined horizontal 7 for the reception of ahorizontally dlSPOBQd bar or member 8, whichis end lower collars 15.ings of the brackets are rectangular to consccured in the openings bythe rear plates or sections 5.. I 1

The bar or member 8, which has pointed terminals 9, isadjustablelongitudinally of .the scraper 1, so as to project a greateror less dlstance from either end of the' scraper.

The projecting portion of the baror mem-- obviate the necessity ofremoving the embankment by pick and shovel.

tudinally of the machine and extending in advance and in rear of theproximate end of her 8 is adapted to penetrate and tear down anembankment at one sideof a road to the scraper and consisting of heavysheet metal, or other suitable material. The guard,

which is approximately oblong, is tapered at its front end and isprovided with a rectangular opening 11- to receive'the bar or member 8,which is square in cross section. The front tapered portion of the guardis provided with a chain '12, .which in-pr'actice, s designed to besecured to the front axle of the machine.- This will strengthen theconnection between the frame of the machine and the excavating devices.The guard is detachable and is adapted to be transferred fromoneend ofthe scraper to theother.

The bar or member 8 is slidable through the openings 7- to projectit'from either end of the scraper, and the said openings 7 arerectangular to conform to the configuration of the bar or member.v

In order toenable the scraper to tear up gravelly and other hard.ground, it is equipped with a plurality of vertically adustable digglngbars or teeth 13, extending below the lower edge of the scraper andprovided with rectangular shanks 14, extending through vertical openings15 of the brackets. and secured in their adjustment by upper Thevertical openform to the configuration of the squared shanks 14, and thecollars, which are located at the upper and lower faces of the brackets,are equipped with set screws 16 for securing them to the shanks 14. Thelower engaging ends of the bars or teeth 13 are tapered and pointed,but'may be shaped in-any preferred manner to enable them to readilypenetrate lot adjustable ars or teeth and the horizontal bar 8, whichmay be constructed ofany suit- V able material, are preferably made .ofsteel.

. Having thus fully described my invention, what I claim as new anddesire to secure by Letters Patent, is

,1. The combination with a scraper, of a bar or member extendinglongitudinally of the scraper and arranged to' project from either endof the same for tearing down embankments, at the side of a road, andmeans for adjustably securing the bar or member to the scraper.

2. The combination with a scraper, of a bar or member extendinglongitudinally of the scraper and having pointed terminals and slidablyconnected'with the scraper so as to project from either end thereof;

3. The combination with a scraper, of a bar or member disposedlongitudinally of the scraper and projecting from one end thereof fortearing down an embankmentat the side of a road, and a guard arranged atthe end of the scraper from which the bar or member projects to preventthe said end of the scraper from catching in an embankment.

4. The combination with a scraper, of a bar or member disposedlongitudinally of the scraper and projecting from one end thereof fortearing down an embankment at the side of a road, and a guard consistingof a plate arranged at the end of the scraper from which the bar ormember projects and extending ,in' advance and inrear of the I bar ormember extendlng longitudinally of scraper. I

5. The combination with a scraper, of a ,bar or member disposedlongitudinally ofthe scraper and projecting from one end thereof fortearing down an embankment at the side of a road, and 'a guardconsisting of a plateprovided with an opening receiving the bar ormember, said guard being extended in advance andin rear of the scraper.

6. The combination with a scraper, of a bar ormember disposedlongitudinally of the scraper and projecting from one end thereof fortearing down an embankment at the side of aroad, a guard consisting of aplate provided with an opening receiving the bar or member, said guardbeing extended in advance and in rear of the scraper, and a chainconnected with the frontend of the guard.

7. The combination with a scraper, of a bar or member disposedlongitudinally of the scraper and adapted to project there- ;from fortearing down embankments, and a plurality ofv brackets mounted on thescraper and having vertical openings, a bar or menu:

ber arranged to extend through the hori-- zontal openings andadapted toproject from either end of the scraper, and vertically adjustable barsor teeth adjustably mounted in the vertical openings and projectingbelow the lower edge of the scraper.

9. An attachment for road scrapers comprising a plurality of brackets, ahorizontal bar or member .adjustably supported bythe brackets and havingterminal engaging portions, a guard carried by the bar or member, andvertically adjustable bars or teeth also mounted on the brackets. 4

10. The combination with a scraper,-of a bar or member adjustablymounted on the scraper'to project from either end thereof, and areversible guard located at the end of the scraper from which thebar ormember projects and adapted to be changed from a one end of the scraperto the other.

11. The combination with a scraper, of a bar or member adjustablymounted on the scraper to project from .either end thereof,

and a reversible guard located at the end of I the scraper from whichthe bar or member projects and adapted to be changed from one end of thescraper to the other, said guard being sup ortedby the bar or member.

12. The combinationwith' a scraper, of a the scraper and slidablyconnected therewith so as to project from either end thereof.

13. The combination with a scraper, of a plurality of spaced teeth orbars mounted on the scraper blade atthe back thereof and depending belowthe lower edge'of'the said scraper blade.

'14. The combination with a scraper, of a plurality of brackets securedto the scraper at the rear face thereof and spaced apart, verticallyadjustable bars or teeth mounted in the brackets and depending below thelower edge of the scraper, and means for securing the bars or teeth in:their adjustment.
